The Chinese patent application No. 200910190150.2 discloses a method for opening and closing a working umbrella by using a magnet or an adhesive pad, and the method is simpler, but has higher requirements on the attraction force of the adopted magnet or the adhesive force of the adhesive pad: if the working umbrella is too weak, the working umbrella in a closed state cannot be pulled back to the initial point of the working stroke; if it is too strong, it is difficult to separate the upper and lower sliders that are sucked together. The method has high control difficulty and is easy to cause the situation that the acting umbrella cannot be opened or closed.
The Chinese patent application No. 201110151527.0 discloses an umbrella-type wind power device comprising: work rope set at an angle to the ground; the control box, the sliding cylinder, the acting umbrella and the balancing device are sequentially connected to the acting rope from bottom to top, and the control box is fixed to the acting rope and is wirelessly connected with the central control device; a plurality of strings connected between the umbrella-shaped edge of the acting umbrella and the sliding cylinder; the umbrella control rope is connected between the control box and the sliding cylinder and is controlled by the control box to change the elongation of the umbrella control rope. The invention mainly realizes the opening and closing of the acting umbrella by controlling the tensioning and releasing of the umbrella ropes through the control box, the method is very simple, but the stability of the opening and closing in the air of the acting umbrella is poor, and the implementation process often occupies excessive acting time due to the longer winding of the control ropes when the umbrella is opened, thereby reducing the power generation efficiency. Meanwhile, the applicant also improves the method, namely, the Chinese patent application number 201110322204.3 discloses an umbrella-type wind energy conversion device and system, wherein the device comprises: a track rope; the lower control box is connected with the sliding cylinder through at least one umbrella control rope; a plurality of string acting umbrellas are connected between the umbrella-shaped edge and the sliding cylinder; the upper control box is meshed with the chain for transmission; when the lower control box reaches the working lower limit position relative to the ground, a first prompt signal is sent out to enable the lower control box to shorten an umbrella control rope, so that the acting umbrella is opened under the action of wind power; when the lower control box reaches the upper working limit position relative to the ground, a second prompting signal is sent out to enable the lower control box to release the umbrella control rope, and enable the upper control box to descend along the chain to drive the top of the acting umbrella to move downwards so as to enable the acting umbrella to be folded. The invention can make the opening and closing of the acting umbrella in the air more stable, can effectively prevent the phenomenon of winding caused by too many ropes when the acting umbrella is opened and closed, and can realize stable high-power wind energy conversion. However, the method for controlling the opening and closing of the acting umbrella is mainly realized by up-and-down transmission of the upper control box on the chain and the retraction of the umbrella rope of the lower control box, and the opening and closing of the acting umbrella cannot be realized rapidly, and the problem of excessive occupation of acting time is not completely solved.

s12: after the second driver (42) is unlocked from the stop block (2), the umbrella body (3) drives the second driver (42) to move upwards under the action of wind force;
s13: the umbrella rope (5) is changed into a relaxed state from tension, and the umbrella body (3) is turned over under the action of wind power to be changed into a combined state;
b) The umbrella body is changed from the closed state to the open state:
s21: the second driver (42) and the stop block (2) are in a locking release state, the umbrella rope (5) is in a releasing state, and the umbrella body (3) is turned over to be in a closing state;
s22: the first driver (41) and the second driver (42) move downwards along the cable (1), and the second driver (42) is locked by the locking mechanism (6) after moving downwards to the stop block (2);
s23: the first driver (41) moves upwards along the cable (1), the umbrella body (3) is gradually opened under the action of wind power, and the first driver (41) is driven to move upwards continuously;
s24: after the umbrella body (3) is completely opened, the first driver (41) stops moving upwards, the second driver (42) is connected with the stop block (2) in a locking way through the locking mechanism (6), and the umbrella body (3) is in an opened state.
8. The method of opening and closing a double-drive umbrella-type wind energy conversion device according to claim 7, wherein in step S12, the umbrella body (3) drives the second driver (42) to move upward under the action of wind force, and the first driver (41) moves downward along the cable.
9. The method for opening and closing the double-drive umbrella-type wind energy conversion device according to claim 7, wherein in the step S12 and the step S23, the driver (4) drives the kinetic energy power generation device to generate power when moving upwards under the action of wind power.
10. The method of opening and closing a double-drive umbrella-type wind energy conversion device according to claim 7, wherein in step S23, the distance of the active upward movement of the first driver (41) is at least 1/10 of the distance between the stopper (2) and the first driver (41) in the open state of the umbrella body (3).
